Thanks for taking the time to explain it Speedy. I also helped myself by learning about center axle disconnect, and what it actually is LOL.No, the disconnect happens at the front diff. So when you're in Auto 4WD, it is connected and everything is spinning up front (ready for transfer case to engage clutch plates). But when you're in 2WD, my understanding is the CAD is disconnected and only the outer front axle shafts are moving.
